Apologies, I know I am probably going to feel silly in the end, but I
am having a problem getting a sample EclipseLink project running. I
have a Derby driver defined and the embedded driver is on the
classpath. When I execute the "JPA Tools --> Genertate DDL" I get the
exception below. Note that the complaint is "Class
[sun.jdbc.odbc.JdbcOdbcDriver] not found" not my defined driver.

Thanks for the suggestion, I will do some digging. Actually, though,
this is a brand new Ganymede install and the code is new project I
created to get familiar with Dali JPA and EclipseLink. The entity
classes I did copy from another example, but not the persistence.xml.

there is no JPA implementation included in Ganymede so you must have
TopLink Essentials defined in your project's libraries or through its
dependent projects. Please setup a new user library for EclipseLink and
ensure that it is the only one used in your test case.

If the error persists please post the new error message. You are looking
for org.eclipse.persistence in the stack trace to indicate that
EclipseLink is being used.

Doug,

That is already the case. I have a user library using EclipseLink set
up as my default for JPA. The user library contains eclipselink.jar and
javax.persistence_1.0.0.jar from eclipselink-M10 .

Your reply pointed to me to the problem though. It was that I also had
my Spring user library included and it had TopLink Essentials defined.
